The second best way to avoid pests is

• A. to deny them food, water, or shelter
• B. to keep all doors open
• C. to use poison bait throughout the facility
• D. to maintain air-conditioning

Answer: (A)

Denying pests access to food, water, and shelter is the strongest preventive step because pests thrive only when they can find the basics they need to survive. When a facility is clean, food is stored properly, leaks are fixed, waste is contained, and entry points are sealed, there’s simply less attraction and fewer opportunities for pests to establish themselves, which makes infestations far less likely. Keeping doors open or relying on chemical controls works against pests after they’ve arrived or tried to enter, and can create safety and environmental concerns; maintaining air-conditioning may improve comfort but doesn’t eliminate the root problem of available resources for pests.
